I was playing fine last night after the patch, got an email telling me I could put my pre-order and early access code in so I went and did that this morning via the psn store as instructed.

Downloaded and installed fine, started the game and it ran a very long update.

Now whenever I try and log in, I get the error:

Unable to complete version check
[20458][24530][20457][404]

I have tried restarting the ps4, exiting the game entirely and re-running several times and nothing is working!
